Product Description

The Naim CD555 CD player (available on 0% finance) makes no attempt to play DVDs, DVD-As or SACDs. It does not have a digital output. Nor does it have a variable output. The CD555 simply plays CDs and at that it excels. Naim created the CD555 in full confidence that it is the best CD player ever made.

First shown and demonstrated at The Hi-fi and Home Entertainment Show in September 2005, Naim's reference CD player, the CD555 with 555 PS delivers the ultimate musical performance from a CD. Please find further information from Naim below.

Dedicated separate power supply

This reference level CD player include a separate power supply from a transformer secondary winding, which is triple regulated, right through to the critical master clock and de-jittering circuitry. Special attention has also been paid to reducing capacitive coupling of high frequency noise from other supplies into this super quiet clock supply through interconnect cables and wiring looms.

Two Burndy interconnects between the power supply and head unit discretely carry the digital and analogue supplies, and extend the principle of reducing capacitive coupling between power supplies as far as possible.

The power supply incorporates significant upgrades over existing designs. More regulators have been used to isolate the supplies to various parts of the circuit, minimising their interaction.

Reference DACs

The CD555 Digital-to-Analogue Converters are mounted in a "quiet room". Apart from ensuring that all critical signals reaching the DAC have immeasurably low jitter the chips are inside a shielded enclosure to keep their environment free of the varying electric and magnetic fields that inevitably occur in a CD player, so enabling the converters to do their work, isolated from all external influences.

We are here to help find the right system for you. As a suggested starting point, you may want to consider partnering the CD555 with the following:

- 555 PS- NAC 252- 552 PS- NAP 500- 500 PS- Ovator S-600

The main CD playing unit features many reference design features, including:

The matching power supply is designed to get the very best sound from the CD555, with design features including:

- Seven regulated power supplies including a separate one for the clock circuitry.- Five secondary windings on the transformer.- A transformer that is 40 per cent larger than that in the XPS2.- Separate dedicated analogue and digital output sockets (Burndy) to minimise high frequency noise modulation of analogue supplies.- Backward compatibility with the CDS3 and CDX2.- Can be used to enhance the performance of the Naim HDX hard disk player or DAC.- A low resonance case with isolating feet.
